Final answer:
An EDI system allows for electronic business transactions between companies, streamlining ordering and invoicing processes. It is supported by the evolution of computing and networks, with roots in early systems like SABRE and conceptual proposals like Licklider's network.
Step-by-step explanation:
An EDI (Electronic Data Interchange) system allows a company's business units to submit orders, issue invoices, and conduct business electronically with other company units as well as outside companies. EDI is a set of standards for exchanging information between computer systems, which has been instrumental in streamlining processes and increasing efficiency in various industries. The historical development of computing and networks, going back to the creation of SABRE by IBM and concepts like JCR Licklider's "Intergalactic Computer Network", laid the groundwork for today's advanced communication systems, including EDI. In contrast to other options like the Internet, an intranet, or electronic point of sale systems (EPOS), EDI specifically refers to the structured transmission of data between organizations by electronic means.
